Heat and hunger --- I agree these factors can definitely negatively impact a negotiation but they can also work in your favour (on occasions). I had an interlocuter who was struggling in the heat and humidity after a long site walk which was in their lunch break. When we put forward our requests at the end of that walk they pushed back but then conceded rather quickly after they saw we weren't giving up as they seemed very keen to just get out of that environment and back to the aircon and their lunch.
